Relay
Contact Life
Relay contacts are available in a variety of metals and alloys,
sizes and styles. There is no such thing as a universal
contact. The relay user should select contact materials,
ratings, and styles to meet, as precisely as possible, the
requirements of a particular application. Failure to do so can
result in contact problems and even early contact failure.
